AHP2224 specifically recognises VPS34 (vacuolar protein sorting 34), otherwise known as PI3-kinase type 3 (PIK3C3), a ubiquitously expressed class III PI3K (phosphoinositide 3-kinase), and member of the PI3/PI4-kinase family, which specifically utilizes phosphatidylinositol (PtdIn) as a substrate, and functions as the catalytic subunit of the PI3K complex.
VPS34 plays a role in the transport of lysosomal enzyme precursors to lysosomes, and in endocytosis and vesicular trafficking, and has been strongly implicated as a regulator of autophagy, forming a multi-protein complex with the proautophagic tumor suppressors Beclin1/Atg6, Bif-1, and UVRAG, in the initiation of autophagosome formation. Distinct complexes of VPS34 have been shown to regulate endocytic processes vital for late-stage autophagosome-lysosome fusion.
AHP2224 has been tested in immunofluorescence using HUVEC cells, in conjunction with Hoescht 33342 (blue) nuclear staining.

Where this product has not been tested for use in a particular technique this does not necessarily exclude its use in such procedures. Suggested working dilutions are given as a guide only. It is recommended that the user titrates the product for use in their own system using appropriate negative/positive controls.
Western Blotting
AHP224 detects a band of approximately 105kDa in HEK-293T cell lysates.
Storage
Store at +4oC or at -20oC if preferred.
Storage in frost-free freezers is not recommended.
This product should be stored undiluted. Avoid repeated freezing and thawing as this may denature the antibody. Should this product contain a precipitate we recommend microcentrifugation before use.
Shelf Life
18 months from date of despatch.
Antiserum Preparation
Antiserum to human VSP34 was raised by repeated immunisation of rabbits with highly purified antigen. Purified IgG was prepared by affinity chromatography.
